Acceleration Formula

What is Acceleration?

The time-rate of change of velocity is called acceleration. Acceleration is a vector quantity which is defined as "the rate at which an object changes its velocity.” Issac Newton is credited as the Founding formula of acceleration. He was the 1st scientist to determine that all moving objects had its own acceleration.
Acceleration is described as the change in velocity over time. It is a vector quantity, acceleration is the rate at which the velocity changes. In general term, acceleration is used for an increase in velocity and a decrease in velocity is known as deceleration.
Let’s see the Acceleration Formula-
a = (vf – vi)/ t (Acceleration is designated by ‘a’.)
 We everybody know that Acceleration,Force and Velocity ,these all are related to one another.So lets get some knowledge on Formula for Force and Formula for Velocity.

Take an Example on Acceleration formula:
If a train moved at final velocity of  31 m/s and if it took  20 seconds to reach the final velocity from the standing point,than what is the acceleration  speed of the train?
a=vf-vi/t
a=31m/s -0 m/s/20 sec(divided by)
a= 1.55 m/s2

This is how  using Acceleration Formula we can solved problems.
